Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
In the series by Bornemeier et al this occured in 14% of their cases. The remaining single artery is often quite large approaching the size of the umbilical vein. Sonography is often able to accurately diagnose this condition, especially with the use of color Doppler flow imaging. There are reports however, of sensitivities and positive predictive accuracies of only 65%.
